+# Map Setup Guide
+
+This guide explains how to set up the world map feature with Xaero's World Map PNG files.
+
+## Prerequisites
+
+1. **Xaero's World Map Mod**: Install the Xaero's World Map mod on your Minecraft server
+2. **Map Generation**: Generate the world map by exploring your Minecraft world
+3. **PNG Export**: Export the map as PNG files using Xaero's World Map
+
+## Step 1: Generate Map in Minecraft
+
+1. Install Xaero's World Map mod on your Minecraft server
+2. Have players explore the world to generate map data
+3. The mod will automatically create PNG files in the server's data directory
+
+## Step 2: Locate PNG Files
+
+The PNG files are typically located in:
+```
+<server_directory>/world/XaeroWaypoints/dim0/
+```
+
+Look for files named like:
+- `xaero_map_0_0.png`
+- `xaero_map_1_0.png`
+- `xaero_map_0_1.png`
+- etc.
+
+## Step 3: Upload Files to Backend Container
+
+The map tiles should be uploaded to the backend container's `uploads/map/` directory:
+
+1. **For Docker Setup**: Upload PNG files to the `uploads/map/` directory inside the backend container
+2. **For Direct Upload**: Use the file upload functionality in your admin panel to upload PNG files to `uploads/map/`
+3. **File Naming**: Ensure files follow the pattern `xaero_map_x_y.png` (e.g., `xaero_map_0_0.png`, `xaero_map_1_0.png`)
+
+**Note**: The map assembly process automatically looks for tiles in the backend's `uploads/map/` directory.
+
+## Step 4: Run Map Assembly
+
+1. Go to `/admin/map-management` in your admin panel
+2. Click "Karten-Zusammenstellung starten"
+3. The system will automatically process all PNG files and create the web map
+
+## Troubleshooting
+
+### No Tiles Found
+- Ensure PNG files are in the correct directory
+- Check that files follow the naming pattern `xaero_map_x_y.png`
+- Verify file permissions allow the server to read the files
+
+### Assembly Fails
+- Check server logs for error messages
+- Ensure sufficient disk space for processing
+- Verify PNG files are not corrupted
+
+### Map Not Displaying
+- Check that the assembly completed successfully
+- Verify the `map-metadata.json` file was created
+- Ensure the frontend can access the generated map tiles
+
+## Example Directory Structure
+
+```
+projekt_vollidion_website/
+├── map-tiles/
+│   ├── xaero_map_0_0.png
+│   ├── xaero_map_1_0.png
+│   ├── xaero_map_0_1.png
+│   ├── xaero_map_1_1.png
+│   └── ...
+├── backend/
+├── frontend/
+└── ...
+```
+
+## Performance Notes
+
+- Large maps (100+ tiles) may take several minutes to process
+- The assembly process is memory-intensive for very large maps
+- Consider using a powerful server for initial map generation
+
+## Support
+
+If you encounter issues:
+1. Check the browser console for JavaScript errors
+2. Review the server logs for backend errors
+3. Verify all PNG files are valid and accessible
+4. Ensure the map-tiles directory exists and is writable
